CEMENT BATCH BOX, CARRIER, AND DUM P.

Application filed January 31, 1923. Serial No. 616,120.

T 0 all whom it mag concern.

Be it known that I, JOHN XV. MADIGAN, a citizen of the-United States, residing at Connellsville, in the county of Fayette and State of Pennsylvania, have invented a new and Improved Cement Batch Box, Carrier, and Dump, of which the following is a specilication.

This invention is an improved means for handling cement for concrete batch box mixers, withoutexposing the cement to the elements and with as little labor as possible.

Primarily the said invention has for its purpose to provide a cement handling means of the character stated ot' a relatively simple and inexpensive construction, by which the. cement load, necessary for the batch to be mixed, can be conveniently and expeditiouslytransported from the cement house or'car' to a concrete mixer, without danger of getting wet, and the cement load held in position for being readily dumped for mixing with the stone and sand that constitutes parts of the batch to be made, and the batch of cement, stone and sand held for being freely discharged (by sliding out of the end of the batch box) into the hopper ot' a concrete mixer.

\Vith the above objects'an'd other'objects hereinafter mentioned in view, my invention generically eomprehends an improved construction of cement receivingbox, a-dump truck having provision for supporting the cement box or boxes thereon in rigid relation thereto-when the batch of concrete to -be mixed will not require enough cement to till the box; means being provided for in.-.

verting the concrete holding box to dump the load when thebox is filled, other means being also includedfor locking the cement box to the upright position and for discharging the cement therein contained through the bottom of thebox into the mixing compartment of the dump truck. Subordinately my invention consists in the peculiar and novel construction of parts that constitute the cement holding andtransporting box, a batch box in the nature of a dumping truck and means for supporting the loaded cement box or boxes thereon in rigid relation to the dumping truck when it is desired to deliver the cement into the batch compartment of the truck, through the bottom of the cement holding box; and other means for pivotally sustaining the said box to adapt it for being inverted and its contents dumped through the top thereof when holding a filled load, all of which Will be fully stated in the following description, specifically mentioned in the appended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of an operative assembly of my complete improved means for producing and handling batches of concrete ready for being received into a concrete mixer, the several cement holding boxes being in rigid relation to the batch box or truck, the parts being shown in full lines in position for being transported to a concrete mixer and in dotted lines in position for dumping a prepared concrete batch into a concrete mixer.

for holding; the box. rigidly As before generally noted, my improved means for handling cement preparatory to I design, best shown in Figures 4,5 and 6,

from which it will be noticed the box 1, which 'in practice, is oi: heavy sheet metal, and is of a sizetohold a proper amount of cement to supply the mixture for one batch i of concrete.

, box top is closed by a lid 2 hinged? along the" The box 1, preferablvl'o f rectangular shape, has a. straight across open bottom nor- 1 mally closed by a door 3 hinged to one of thelong side edges of the box, to pendently swing therefrom when released from certain lock devices that hold it normally closed,

and as presently further explained.

The top of the box is bevelle or inclined downwardly from the front to t e rear side,

as is best shown in Figure 4, and the said lower edge of the box top to provide for dropping to the pendentopen position when the boxis inverted, duringthe operation ofdumping. a full batch or loadof cement into the mixing compartment of the dumping trough or truck, and as is clearly illustrated in Figure 2 of the, drawings. 3 At the opposite ends of the box, are secured castings, in the nature of elongated plates 4 -5 each of which has an eye 17 for receiving the hooks 27 27 on the. ends of the hanger cable 27-27 that constitute parts of an overhead carrier (not shown) by which the fully or partly loaded boxes, .1 are'lifted and for delivering the same to their respective mixing compartments in the truck or body A. Y-

Each casting a and 5 is also provided with a trunnion 18 and it should be mentioned that the opposite trunnions1818 are located far enough below the center of gravity of the filled cement boxes, so that the box will revert itself when lock released from in the manner best understood by referring to Figure 2 of the drawingsand explained as follows: i

' n The batch box or truck, designated A, is preferably divided into a plurality of oompartments abc, and for each of the compa rtments a--b-c is provided a pair of oppositely disposed standards 20- -20 that include downwardlydiverging lugs 2O'--'-20 adapted for being attached to the outside of the trough or box A in any approved manner. I

The upper end of each standard 20 extendssome distance above the batch box A and terminates in a head having an open pendent slot B, the slots in the'opposite standards constituting the bearings for the "trunnions 18 on the boxes 1, the shape of the bearing slot 13 fatcilitatingthe lowering of the trunnions 18 of the cement'boxes 1 into their respective sets'of standards when the boxes have been carried into position for being mounted onto the said standards 20, the

latter also, serving to support the cement I boxes in place on the batch box or truck A as the said truck 1S transported and positioned for dumping the concrete batches into the hopper of a concrete mixer.

One of the end castings 5, of each box 1,

has a U shaped locking lug 19 adapted to receive a latch or detent-22 whichincludes a tubular portion 22 that rockably engages a bolt 23 mounted; in opposite end bearings 21 secured, by bolt and nut connections 22 to ,the standard-fld as is clearly shown in Figurest) and '10, from which it will be no ticed thedetent or locking device 22 is located near the crotch end of the standard 20 and in position for readily dropping into or lifted out of engagement with the lock ng lug 19 on the box 1, it being understoodthat when the detent engages the said lug 191the box is held in a relatively rigid upright posi' tion above the truck or body A when the said truck A is being transported in order that there shall be no, turning motion of the cement box until it is ready for being inverted and unloaded through the top thereof.

lln the practical application of my invention, the batch box A is suitably fulcrumed on a pivot 50.looated sufiiciently nearone end (see Figure 1) to permit of readily swinging the said box A to the dumping position. (indicated in dotted lines in said Figure 1) to thereby provide for freely sliding out the concrete batches. gathered in the several successive compartments 0;Z 0; the said several compartments including swinging end gates 26, in practice, latch at the start the several end gates serve'as end closures for the several separate compare ments of the trough, as shown. its supporting standard on the mixing truck,

As before mentioned. my improved construction of cement holding box is adapted; according to the load contained therein, "for -be1ng emptied either through the top, when mechanism for the bottom door 3) the construction of which is best shown in Figures 7 and 8. The door 3 includes an angled brace member 14 that extends along the unhinged edge of its bottom, which edge projects beyond the front side of the box 1, as is best shown in Figure 8.

()n the Iprojected end of the door 3 is secured a vertically disposed angled plate 6 whose upper end terminates in an upwardly 90 of a pull'rod' or lever Qslidably mounted in a bearing'll on the box' 1, and the said rod 9 extends beyond one end of the box and terminates in a.- bent handle 91; 1O designates a compression spring mounted on the rod 9 with one end bearing against a washer 16 that engages the bearing 11. The other end engages a washer 15 that bears against the flattened end 90 of the rod, the arrangement of the several members doscrihed being such that when the latch is pulled in the direction 'of the arrow :1, on Figure 7, the latch 7 will be swung from connection with the bevelled flange 60, release the door and thus permit it to drop to the pcndentposition shown in Figure 3, it being understood that the door'at the bottom amply provides for cleaning the cement box after it is dumped or unloaded.

O pew/Mon,

or partly filling the box with cement. The

lid 2 is then closed and owing to the inclination of the box top it sheds the water, in case of rain, and therby provides for, handling the batch or load of cement without exposing it to the elements. v I

The lifting hooks 27-27,,0f an overhead carrier, are then attached to the ears 17-47 on the box 1, (see Figure 5) and through the overhead carrier the loaded box is lifted from the floor of the cement house or car, conveyed to and lowered'onto the. standards 20, that project. above the concrete elements receiving compartment on the truzk A, it; being understood that the lowering of the cement box onto the opposing set of stand ards 20-20 is facilitated by the diagonally inclined openway bearings B-B into which the trunnions 18-18 of the box are received; it being also apparent that since the trun nions 18 are located at a point below the center ofgravity of'the loaded box 1 when filled, the said box normally tends to tilt in the direction of the arrow y when positioned, as on Figure 1. i

. To hold the cement box 1 in rigid upright position relatively to the truck or portable trough A, after the box 1 has been mounted on the standards 1818, the detent 22, before mentioned, manipulated by a lifting rope is lowered to interlock with the U shaped locking lug 19 on the box 1, and

thereby sustains the said box 1 in its vertical position as the port-able trough or truck A adjacent the concrete mixer is positioned to discharge a batch of aggregate and cement into the hopper of such mixer.

As before stated, the compartmentsaZ)c of the portable trough or truck A'are formed between latch equipped, pendentlyhinged end gates 26, and assuming the batch of stone and sand as having been placed in, say the outermost compartment a, the locking detent 22. is' raised out of engagement with the lug 19 and the box 1 having a filled load, when released, will revolve on its trunnions (the latch '22 being new released). and invert itself, as shown in Figure 2 and dump its load of'cement into the compartment a of the truck A. By then releasing the front end gate 26 and tilting the truck holder A to the position indicated 1 in dotted lines on Figure 1, the cement, to--' gether with the stone and sand, constituting a concrete batch, will slide out of the said compartment to into the hopper of the concrete mixer, to be worked by such mixer,

When a plurality of compartments are formed vinthe truck or trough box A, as in dicated in Figure l, by unlatching their're spective end gates 26 the successive compartments Z) and c are emptied of their conloo tents in the same manner that compartment I a is'cleared. a

The bottom door 3 of the cement box 1, which provides for conveniently 'cleanin the said cement boxes, as before noted, also timebatch of concrete to be mixed will not require enough cement to fill the box 1 and they tions for dumping the cement when the their upright positions by the detents 22 mentioned and the several compartments are cleared of the concrete batches contained therein in the manner explained as follows:

In order to dump the'c'ement from the box 1, the box being at its upright position, the rod 9 is pulled out in the direction of ically inverting the box and. dischargi the arrow which causes the detent 'i' to turn on its pivot bolt 13 and release its head 70 from the bevelled flange 60 of the plate 6 secured to the free end of the door 3, which latter being thus released drops to a-pendent position and permit the cement to discharge through the bottom of the box 1 into the compartment of the portable body. A from which (the end gate of the said compartment being unlatched) the batch, as the body A is tilted, will slide out into the hopper of the concrete mixer, it being obvious that the latch devices 7 and dare so arranged that when the door 3 is swung upward it will force the angled flange 60 past the locking head 70 of the device 7 and cause its upper end to slightly compress the spring 10 which, as the lower edge of the flange 60 passes the hook on the head 70 due to its compression, causes the latch 7 and the member 60 to again interlock and hold the door 3 in a rigidly closed position.

My improved vconstructionat cement holding box which provides for handling'the cement from the time it' leaves the cemen house until it is dumped intothe stone and sand batch, without exposing the same to the weather and also provides for automatically dumping a filled load byautomatng the cement through the top thereof.
